The EK Quantum Vector3 GPU Block Master RTX 5090 Plexi features a nickel plated copper cold plate, a clear acrylic top, and a full coverage black aluminium backplate to provide efficient cooling for the GPU. With pre-cut thermal pads, addressable D-RGB lighting, and optimised coolant flow, the water block supports compatible Gigabyte AORUS RTX 5090 Master, Master Ice, Xtreme Waterforce, and Gigabyte RTX 5090 Gaming OC graphics cards.
Features
EK-Quantum Vector³ Master RTX 5090 - Plexi
Engineered for the Gigabyte AORUS GeForce RTX™ 5090 MASTER and Gigabyte GeForce RTX™ 5090 GAMING OC 32G models, the EK-Quantum Vector³ Master RTX 5090 - Plexi delivers elite thermal performance for enthusiasts who demand more. Featuring EK’s expanded next-gen cooling engine, pre-cut high-performance thermal pads, and an advanced gasket design, this block ensures your GPU stays cool and efficient - even under the heaviest gaming, rendering, or overclocking loads.
Next-Gen Cooling Engine – Bigger, Faster, Cooler
With an enhanced fin array and precision-optimised coolant flow paths, the Vector³ Master RTX 5090 raises the bar in thermal performance:
- Optimised Open Split-Flow Design: Uniform coolant distribution and minimal flow restriction ensure top performance in both standard and reverse flow setups.
- Low Hydraulic Restriction: Compatible with high-performance and low-speed pump systems alike—perfect for silent or maximum throughput builds.
- Full Component Cooling: Actively cools the GPU core, GDDR7 VRAM, and power stages while passively lowering temperatures on critical PCB hotspots via the included backplate.
Ideal for overclockers and creators pushing the RTX 5090 to its limits, this block keeps thermals in check, so your GPU can maintain peak performance longer.
Precision Materials. Premium Build
Every Vector³ block is crafted from industry-leading materials for both performance and longevity:
- Nickel-Plated Electrolytic Copper Cold plate: Maximises heat transfer with supreme durability.
- CNC-Machined Cast Acrylic Top: Crystal-clear view of your coolant with impeccable polish and shine.
- Black Anodised Aluminium Backplate: Increases cooling surface area while structurally reinforcing the GPU.
- Single O-Ring Seal: Simplifies maintenance and reduces potential failure points.
- New Anti-Debris Gasket System: Prevents solid particles from collecting inside the cooling engine for consistent, long-term performance.
Pre-Cut Thermal Pads for Effortless Installation
Comes with EK’s new-generation thermal pads that are partially pre-cut for a clean, precise fit, maximising heat transfer from VRAM and VRM components with minimal setup effort.
Included Full-Coverage Backplate
A sleek, black, full-coverage backplate comes included, enhancing both the look and cooling efficiency of your GPU. Its distinctive L-shaped profile fully encloses the card for a seamless appearance while increasing passive heat dissipation. Pre-installed captive screws make installation simple and ensure perfect alignment every time.
EK-Matrix7 Support - For the Cleanest, Easiest Loop Building
Designed to align with the EK-Matrix7 standard, this block makes planning and building your liquid cooling loop faster and easier:
- Seamless integration with EK-Quantum Reflection² distro plates.
- Effortless tube routing and bending with precisely aligned ports.
- Perfect fit whether your GPU is mounted vertically or horizontally - clean lines, pro finish.
Addressable D-RGB Compatibility
Addressable D-RGB LED lighting is deployed on the longest edge of both top and backside water blocks for improved uniformity and brightness. The PCB and diodes are concealed inside a clean aluminium extrusion. The individually addressable RGB LED is compatible with popular RGB sync technologies from all major motherboard manufacturers. The arrow marking on the 3-pin D-RGB LED connector is to be aligned with the +5V marking on the D-RGB (addressable) header (Pinout: +5V | Data | Blocked | Ground).
Please Note:
- Due to an immense variety of fittings/barbs available on the market and no prescribed standards, EK Waterblocks guarantee compatibility only for connectors bought from EK Waterblocks' website.
- Factory backplates are not compatible with this water block.
- This product should NOT be installed with any aluminium liquid cooling parts.
- The use of specifically engineered coolants that contain corrosion, scale, and biological inhibitors is mandatory to prevent damage to your nickel-plated water block! EK is offering a selection of such products in the coolants section.
- This product is compatible with EK-Quantum Scalar² Terminals, but no longer Matrix7 Compatible if stock terminal is replaced.
- To leak test the EK-Quantum Vector³ water block, EK recommends 0.6 (+/-0.05) bars of pressure for 2 minutes.
